SPRINGFIELD — Before Aaron Collins died, he gave his brother, Seth, a mission: Eat, be merry and leave a giant tip.

On Wednesday night, Seth Collins, of Lexington, Ky., did just that, leaving a $500 tip for a Friendly’s waitress in Springfield. It’s part of a nationwide tour that Collins is carrying out in the name of his brother, who died in July 2012 at the age of 30.

In a story provided by the Eagle Times of Claremont, N.H., the Friendly’s waitress, Julie Bombria, said she thought she was going to faint after getting the generous tip.

“This is the nicest thing anyone has done,” she said.

In his will, Aaron Collins asked his family to give his money to people in need. His cause of death is still unknown, according to the newspaper. Through his family, he’s given away 81 tips throughout the Midwest, Pacific region and western mountains and is now in New England.

Initially, Seth Collins took family and friends to dinner at a Lexington restaurant, gave their server $500 and recorded it. His brother’s wish was fulfilled but far from over. Seth Collins put a video of his first tipping spree on Facebook and started getting donations from around the world. The total’s up to $50,000.

“(Aaron) thought it would be a one-shot deal,” Collins said. “I was going to do this like three or four times, but people were so compelled that they kept giving money. I’m going to give it back on behalf of my brother.”

He is on his way to Maine, then he will work his way down through New Hampshire, Massachusetts, Rhode Island and the Mid-Atlantic.

“Being on the other side of the table and giving away $500 tips is very rewarding,” Collins said.
